iIIPE-COUPLING.

'1 'u all whom) it may concern:

.lie it known that I, JonN'P. BUTLER, a citizen of the lmted States,residing at ll'averhilh iu the county of Essex and State ofh'lassachusctts, have invented certain new and useful Improvements inPipe-tlouplings, of which the following is a specification, referencebeing had to the accompanying drawings.

This inventiou relates to new and useful improvements in pipe couplingsand more particularly to a coupling used in connection with a lead bendon a closet fitting and my object is to provide a simple and inexpensivejoint which will effectively secure the lead bend to the fitting andthereby eliminate the necessity of using the brass and expensivefittings which are usually used in connectionwith devices of thischaracter. i I

'A further object of the invention resides in roviding an annularflange: or a casting an a removable annulus on the lead pipe, saidmembers being adapted to-be secured together to securel retain the pipesections together and a stil further object resides in so designing theend of the lead pipe section as to provide anannular flange thereonadapted to be disposed between the annulus andthe aforesaid annularflange.

With these and other objects in View, the

invention consists in the novel features of construction, combinationand arrangement of parts aswill be hereinafter referred to and moreparticularly pointed out in the specification and claim.

In the accompanying drawing forming a art of. this application, Figure 1is a vertical longitudinal section therethrough. Fig. 2 is a perspectiveview of the annulus removed, and Fig. 3 is an enlarged fragmentarysection through the coupling showing the parts separated.

In describing my invention, I shall refer to the drawing in whichsimilar reference characters designate corresponding parts throughoutt'heseveral views and in which- 1 indicates a waste pipe adapted for usein connection with closets having the angular extension 2 formed thereonand communieating therewith, said pipe 1, with its extension beingpreferably formed of castiron. The extreme free ends of the extension 2has the peripheral edge thereof beveled as shown at 3, the purpose ofwhich will be hereinafter'more particularly described, and

formed on the outer periphery of this pipe extension 2, adjacent itsfree end is a collar offset portion in the rear of the flange 7. is

an annulus 8, said annulushaving a diametrical measurement equal to asimilar measurement on the collar or flange 4 of the section 2. Theouter face of the annulus 8 1s provided with an annular rib 9, while theouter face of the flange 4 is provided with a similar annular groove 10adapted to receive the rib therein and adapted to be dis posed throughthe annulus 8, the flange 7 and the flange or collar 4, are the tiebolts 11. Nuts '12 are adapted to be engaged with the-threaded ends ofthe bolts 11 and when turned home thereon, the lead pipe section 5 willbe drawn toward the section 2 and the annular .rib 9 which is receivedin the annular groove 10 will bind in said groove a portion of theflange 7 of said lead pipe section. This will form a secure water-tightjoint between. the pipe sections and to also aid in the formation ofsuch a water-tight connection, the beveled edge 8 of the section 2. willbe tightly received in the shoulder formed by the offsetting of the endof the lead pipe section.

From the above description of the construction of my improved pipecoupling, the manner of applying the same to use will be readilyunderstood and it will be seen that I have provided a simple, butpositively water-tight {pint between the pipe sections.

It will furt or be seen that while simple in construction, the joint isinexpensive to manufacture and will eliminate the necessity of the moreexpensive brass joints which are constantly used in connection withcloset fittings.

While I have particularly described the elements best adapted to performthe functions set forth, it is obvious that various changes in form,proportion and in the minor details of constructlon maybe resorted towithout departing from the spirit or sacrificin" any of the principlesof the invention.

:laving thus described this invention, what I claim is Ina pipecoupling, the combination with a pipe section having an annular flangeformed on the outer periphery thereof, at

for-m a water tight joint therebetweemthe extreme free end ofthe secondmentioned pipe sectlon being bent to form an-annular flange thereon,

second pipe section to contact with the annular flange formed thereon,said annulus and flanges on said 'sectlons being provided with I aliningopenings, an annular rib formed on 30 the inner face of the annulus inregistration with the groove of the first mentioned flange, andfastening means extending through the openings in the annulus andthrough said flanges to secure sald plpe sections together. 35
